SPECIFICATION forming part of Letters Patent No. 716,156, dated December16, 1902. Application filed January 28, 1902. Serial No, 91,551. (Nomodel.)

` To a/ZZ whom t may concern.-

Beit known that I, WILLIAM JAMES WHA- LEN, a citizen of the UnitedStates, residing at Pittsburg, in the county of Allegheny and State ofPennsylvania, have invented a new and useful Improvement inRiveting-Ma'- chiues, of which improvement the following y is aspecification.

plan view of the same in This invention relates to new and usefulimprovements iu portable riveting-machines.V

The object of my invention is to` provide a;

simple and practical apparatus ofA the above character adapted to beoperated by hand and which can be manufactured and retailed atcomparatively small' cost.

In the accompanying drawings I have illustrated the :apparatus invarious ways, i whichi Figure 1 is'a longitudinalside View of theapparatus complete. Fig. 2 is a longitudinalV side view ofthe same insection. Fig. 3 isa section' along the line 3 3 of Fig. 2. g

Referring to said drawings for a description of the detail parts of myinvention and their operative arrangement, the numeral 1 designates acasing having the chamber 2 at one end and a block 3 secured within theother end, which block is provided with a handle 4.- Loosely fitted intosaid chamber 2 is the header-die 5,having the concaved recess 5l in itsface.` This die is secured in operativeposi# tion by a rod 6,Whichextends across the `chamber through a `longitudinal opening 6in the rearportion thereof. YA pair of reciprocating plungers 7 are fitted.between'the casing or chamber walls and a lug 8. Theseplungersareprovided with heads 9 for alternate engage-Y mentwith saiddie 5 and at theirrear ends with rounded Shanks 10, which extend into.openings 1l in said block 3. These plungers shaft 14, having rigidlysecured thereto the square cams 15 to engage with upward eXtensions 13on said plungers. These cams are set at an angle of forty-five degreesfrom one another, so that when they are revolved one plunger will beheld in forcible position after the other has spent its force upon thedie. To rotate said cams, I secure to the side of the casing agear-wheel 17 to mesh with a wheel 16 on the cam-shaft and provide theformer with a handcrank 1S. The relative proportion between these wheelsmay be varied for increasing power and increasing or decreasing therotation of the cams.

In Vpractice the device is grasped in one hand by the handle 4E. The dieis then brought intoengagement with the rivet, and by` .a rotary'movement of thecrank with the other hand an alternate reciprocatingmovement is given to the plungers through the medium of the cams, whichplungers, forciblyacting upon the die, will successfully head the rivetin a short time and with an expenditure of 'little force upon the partof the operator.

carriedby said plungers, an apertured block `carrying a handleandureceiqving said Shanks of the plunge'rs,.upward extensionsv carried`bythe plungers with a com monshaft mounted in the casing and carryingcams for engagement with said extensions, and means for operating saidshaft,` substantially as described. t

InV testimony whereof I have hereunto signed my name in the presence oftwo subscribing witnesses. A
